<h1 id="一、前端分层开发"><a href="#一、前端分层开发" class="headerlink" title="一、前端分层开发"></a>一、前端分层开发</h1><p>我们看前端代码，JS和html都放在一起，并不利于我们后期的维护。我们可以在前端代码中也运用MVC的设计模式，将代码进行分离，提高程序的可维护性。</p>
<h2 id="1-自定义服务"><a href="#1-自定义服务" class="headerlink" title="1.自定义服务"></a>1.自定义服务</h2><p>在 AngularJS 中，服务是一个函数或对象，可在你的 AngularJS 应用中使用。我们在上次课中使用了内置服务$http .其实我们也可以自己来定义服务，而服务会封装一些操作。我们在不同的控制器中可以调用同一个服务，这样服务的代码将会被重用。</p>
<p>在js文件夹下创建service文件夹。创建brandService.js前端服务层</p>

<h3 id="1-2后端"><a href="#1-2后端" class="headerlink" title="1.2后端"></a>1.2后端</h3><p>实现思路：我们将规格和规格选项数据合并成一个对象来传递，这时我们需要用一个对象将这两个对象组合起来。在业务逻辑中，得到组合对象中的规格和规格选项列表，插入规格返回规格ID，然后循环插入规格选项。</p>
<p>（1）我们要增加规格选项，必须要知道新增规格的ID, 所以我们在修改pinyougou-dao 的TbSpecificationMapper.xml ，在insert节点后添加如下配置</p>

<p>因为我们在模板控制层中需要使用品牌服务层的方法，所以需要添加<strong>依赖注入</strong>，一旦出现依赖注入要赶紧添加js引入</p>
</blockquote>

<p>（4）修改type_template.html ，添加JS引入——由于这里有依赖注入</p>

<p>特别注意一下，JS引入的位置，要在typeTemplateController.js之前，因为该控制器要使用到它</p>
<p>（5）在type_template.html 用select2组件实现多选下拉框</p>
<pre class="line-numbers language-markup" data-language="markup"><code class="language-markup"><span class="token tag"><span class="token tag"><span class="token punctuation">&lt;</span>input</span> <span class="token attr-name">select2</span>  <span class="token attr-name">select2-model</span><span class="token attr-value"><span class="token punctuation">=</span><span class="token punctuation">"</span>entity.brandIds<span class="token punctuation">"</span></span> <span class="token attr-name">config</span><span class="token attr-value"><span class="token punctuation">=</span><span class="token punctuation">"</span>brandList<span class="token punctuation">"</span></span> <span class="token attr-name">multiple</span> <span class="token attr-name">placeholder</span><span class="token attr-value"><span class="token punctuation">=</span><span class="token punctuation">"</span>选择品牌（可多选）<span class="token punctuation">"</span></span> <span class="token attr-name">class</span><span class="token attr-value"><span class="token punctuation">=</span><span class="token punctuation">"</span>form-control<span class="token punctuation">"</span></span> <span class="token attr-name">type</span><span class="token attr-value"><span class="token punctuation">=</span><span class="token punctuation">"</span>text<span class="token punctuation">"</span></span><span class="token punctuation">/&gt;</span></span>	<span aria-hidden="true" class="line-numbers-rows"><span></span></span></code></pre>
<p>multiple 表示可多选</p>
<p>Config用于配置数据来源</p>
<p>select2-model用于指定用户选择后提交的变量</p>
<p>（6）修改type_template.html ，添加初始化</p>
